Middle-class dentist Rachel Clifford (Ormond), recently separated from her husband, takes a part-time job at a local prison where she becomes attracted to her patient, Cockney charmer Philip Chaney (Roth). He's coming to the end of a 10-year sentence and the lusty duo manage to consummate their relationship during one of Philip's day-releases. Only problem is fellow con Towler (Salmon) notices what's happening and blackmails and threatens Rachel--leading to a violent confrontation. Roth and Ormond click believably as opposites-attract partners though the script has some weak elements.
